Description

Technical Field

[0001] This utility model specifically relates to the technical field of spinning machine accessories, and more specifically to an upper pin assembly capable of discharging static electricity from the main drafting zone. Background Technology

[0002] The upper pin assembly is one of the important drafting components of a ring spinning frame. It works in conjunction with the lower pin and upper and lower rubber rings to form a control jaw within the main drafting zone. The cradle applies pressure, causing the rubber rings between the upper and lower pins to generate friction against the roving sliver, thereby controlling the sliver's movement. By rationally setting the structure and parameters of the upper pin, and through the actions of the spring block, spacer block, and pressure bar, the sliver is subjected to appropriate friction and tension during drafting, controlling the speed change point of the fibers in the floating zone, concentrating fiber speed changes, reducing yarn unevenness caused by accidental drafting, effectively controlling the roving sliver, resulting in uniform and stable yarn evenness, reducing yarn hairiness and breakage, and improving yarn strength and quality.

[0003] However, in practice, it has been noted that the upper pin assembly generally applies downward pressure through a spring. Since the leading edge needs to withstand downward pressure for a long time, it is very easy for the leading edge to be damaged. In addition, most upper pin assemblies have the support frame and the leading edge as one piece. When damaged, the entire upper pin assembly needs to be replaced, which leads to high repair costs and waste of parts. Repair also takes a long time, resulting in low repair efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an upper pin assembly capable of discharging static electricity from the main stretching zone. Through the movable engagement between the detachable fixing pin and the elastic telescopic block, the elastic telescopic block can be easily disassembled and replaced. Furthermore, the limiting fixing seat at the end of the detachable fixing pin serves to limit movement, preventing the elastic telescopic block from slipping off the connection point during movement. This addresses the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An upper pin assembly for discharging static electricity from the main drawing zone includes an integrally formed fixed bracket and elastic claws, wherein both ends of the fixed bracket are integrally provided with extension mounting seats, and each extension mounting seat is fixedly connected with a detachable fixing pin. The detachable fixing pin includes a hollow seat, the end of which has a movable groove, and a support shaft rod fixedly connected to the hollow seat is provided in the movable groove, and a limit fixing seat is installed at the end of the support shaft rod.

[0006] As a further technical solution of this utility model, the elastic telescopic block includes a movable pressure plate located below the hollow seat, and the end of the movable pressure plate is integrally provided with a rotating bushing corresponding to the movable groove, and the rotating bushing is movably connected to the outer side of the support shaft.

[0007] As a further technical solution of this utility model, a metal conductive sheet is embedded at the end of the movable pressure plate away from the rotating bushing, and a wire adapter corresponding to the metal conductive sheet is embedded on the side of the movable pressure plate.

[0025] By adopting the above technical solution, the spring plate 7 can be fixed between the movable pressure plate 51 and the hollow seat 31 through the spring plate slot 52 on the movable pressure plate 51 and the spring plate slot 34 on the hollow seat 31. The elasticity of the spring plate 7 applies downward pressure to the movable pressure plate 51, and the pressure of the leaf spring rocker arm makes the bottom of the movable pressure plate 51 fit tightly with the yarn, and facilitates the timely replacement of the spring plate 7 at the connection.

[0026] More specifically, a spring slot 52 is provided above the movable pressure plate 51, and a spring slot 34 corresponding to the spring slot 52 is provided at the bottom of the hollow seat 31.
